Ok, I bet there's someone out there a lot smarter than me who can tell us what that binary on Ran's tabard means...
absolutely nothing, it's just a bunch of random 0s and 1s for the sake of a joke. And even if it did mean anything, it's improperly formatted so there's no way of telling what that message might be.
All right, since you brought it up, I'll show you.Ran! Come here for a bit.Please regularly reward Ran-san a little more...Eh?Totally wrong.Yes~~, what do you need me for , Yukari-sa...Ran-san is beautiful, strong and smart.I wish to be an adult woman like her.AwawawawawIs it wrong?Wa...wait...!?Eh?

Reference to how a shikigami can be compared to a computer in Curiosities of Lotus AsiaYukari-sama...I think I just heard an unbelievable sound there...She gets like this every time something unexpected happens to her.
